Safety*
The assembly must be installed, maintained
and repaired exclusively by persons familiar
with the instructions.
Always disconnect power source
(electricity, air or hydraulic) from the
equipment when it is not being used.
This equipment generates high pressure.
Extreme caution should be used when
operating this equipment as material leaks
from loose or ruptured components can
inject fluid through the skin and into the
body. If any fluid appears to penetrate the
skin, seek attention from a doctor
immediately. Do not treat injury as a simple
cut. Tell attending doctor exactly what type of
fluid was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Do not exceed the stated maximum
working pressure of the equipment or of
the lowest rated component in your
system.
• Always read and follow the manufacturer’s
recommendations regarding fluid
compatibility, and the use of protective
clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.
CAUTION
Do not operate equipment without
wearing personal protective gear.
Wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing pro-
tection used for appropriate conditions
will reduce personal injuries.
Failure to comply may result in light
personal injury.
WARNING
Do not allow any body part
to be trapped by equipment.
Body parts can be crushed
by subassemblies during
operation.
Failure to comply may result in death
or serious physical injury.
WARNING
Do not allow fluid to leak
onto floor when operating
equipment. If spill occurs,
clean any fluid on floor before continuing
operation.
Failure to comply may result in death
or serious personal injury.
WARNING
Do not use this equipment to supply,
transport, or store hazardous
substances and mixtures in accordance
with annex I part - of the CLP
regulation (EG /) or HCS 

Description
Model  oil pump is used as the
pumping unit for a centralized lubrication
system having a single line circuit of SL-,
SL-, SL- or SL- injectors.
It is an air operated reciprocating pump
that discharges an established amount of
lubricant (.in(, cm))) into the
circuit for each pump cycle.
This pump can be used with an air control
system, a time control and a pressure switch
supplied by the owner/operator.
WARNING
Do not operate unit with combustible
gas.
Failure to comply may result in
serious personal injury and/or damage
to the equipment.
) Based on lubricants that are free of entrapped air. Lubricants that are aerated will reduce output of pump.
NOTE
Pressure is set and controlled through
pressure switch.

Operation
Lube cycle initiates when pump times out.
Air solenoid is energized to deliver air to
pump and vent valve. Pump dispenses
lubricant through injectors to bearings. Once
all bearings receive lubricant, pressure rises
in system to actuate pressure switch. When
pressure switch actuates, control is reset to
de-energize solenoid valve, cutting off air to
pump and vent valve. Pump stops, pressure
vents and pressure switch de-actuates.
Control begins timing toward next lube
event.
To prime system
Supply lines
Allow lubricant to bleed around vent plug to
expel air pockets trapped between pump
and supply line connection. Continue
operating pump until lubricant flows around
any plug.
Feeder lines
Fill each feed line with lubricant before
connecting lines to outlets of injectors and
bearings to prevent having to cycle each
injector.
Injectors
Check injectors for proper operation by
observing movement of indicator stems.
To fill reservoir
Lubricant reservoir is filled through
filler cap () at top of reservoir. Strainer ()
is located in filler cap. Strainer should be
removed from filler cap and cleaned
periodically.
To lubricate air valve
mechanism
Refer to Fig. IPB , page .
 Disconnect air to pump.
 Remove four cover screws (),
cover plate () and cover plate
gasket ().
 Remove and disassemble
air valve casting () from pump.
 Clean or flush air valve casting to remove
any chips, or other foreign particles prior
to reassembly.
 Pack cavity with grease before replacing
toggle assembly (). Use approximately
 /ounces ( ml) NLGI  light grade
water repellent grease.
 Replace cover gasket, cover and screws.
Tighten to avoid air leaks.
 Inspect parts at least once each year.
Vent valve
Vent valve () operates with compressed air
from same source that operates pump.
When pump is in operation, air pressure
keeps vent valve closed and lubricant is
directed through outlet to injectors. When air
to pump is shut off, vent valve opens and
supply line pressure vents back into
reservoir.
Safety unloader
Safety unloader () is provided at pump
outlet to prevent build-up of dangerously
high lubricant pressure in system. It is fac-
tory set to open at approximately
  psi to   psi ( to  bar).
WARNING
Safety unloader requires no adjustment
and should not be tampered with.
Failure to comply may result in death
or serious injury.

Troubleshooting
Problem Cause Solution
Pump operates continuously. Pump has lost prime. Examine lubricant supply. Refill reservoir
if necessary.
Air pocket trapped in lubricant. Loosen vent plug one turn. Allow pump to
operate until trapped air is pumped out.
Close vent plug.
Pump continues to operate without discharging
lubricant.
Pump check () and steel ball ()
fouled.
Remove and clean checks and check seats.
Vent valve () fouled. Replace vent valve.
Foreign material prevents needle ()
from seating properly.
Clean or replace parts.
Pump fails to operate. Air system is leaking. Verify air supply is connected.
Verify air system is not leaking.
Injectors fail to cycle. Leak in supply line. Examine lines and connections.
